PAPER-PERFORATING MACHINE.

s'rEcIrIcA'rIoN forming part of Letters Patent No. 291,293, dated January 1, 1884.

Application filed March 5, 1883. (Modem To all whom it may concern.-

Be it known that I, ISRAEL CURTIS CARPEN- TER, a citizen of the United States of America, residing at Cherry Creek, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Machines for Perforating Paper, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of this invention is to produce a machine that will perforate paper for the use of silk-growers who require that the perfora tions be at certain distances apart, and in different sheets to be of increasing size, as is well known, so that the growing worms can crawl up through the perforations to obtain the food placed on top, while the under sheets are removed as-fast as they become soiled and the worms leave them for that above; and my invention consists in the construction as hereinafter claimed. 7

In the drawings, Figure 1 is a side elevation of the machine in longitudinal sectionin line of m m, Fig. '3, certain parts being unbroken; Fig. 2, an elevation of the side re moved from Fig. 1; Fig. 3, a top plan of the whole device; Fig. 4, an end view in cross-section in line of w m, Fig. 3.

A A represent the lower sides of the upright framework, and A the upper side pieces, leaving aspace, a, for the moving frame or carriage B to work sidewise and forward in, which holds and carries the sheets to be perforated, usually from five to fifteen sheets at once. This carriage B has two movements, one sidewise, on the outlying frames b b, which carries the paper one notch or tooth of the ratchet-rack c, which forms part of the carriage, and is operated by a ratchet-bar, d, swung above it by links 3 y, (see Figs. 1, 3, 4,) and with a long guide-bar, d, passing through one side of the frame-work A. (See Figs. 3 and at.) This carriage is moved one tooth automatically by the action of the punch bar'e and its lever f, as hereinafter explained. The other movement of the carriage B is toward the operator of the lever f, to bring the paper forward just sofar to present a fresh line to be perforated. This is done by a ratchet-wheel, g, on the outside of frame A, connected by the same axle to a grooved wheel, 9, inside the frame, around which runs a rope, h, one end fastened to one end of carriage B, and the other end to the opposite end of said carriage. (See Figs. 1 and 3.) This ratchet-wheel gis operated by along ratchet, 13, on a lever, j, the teeth of the wheel being so cut or set as to bring the carriage forward just one tooth at each movement of lever j, and thus present a new line on the paper below the others to be perforated by the punch. WVhen a greater or less distance be-' tween the rows to be punched is required, different wheels with greater or less space between the ratchets are used, and the teeth on this wheel 9 and the teeth on the rack 0 will always correspond, so as to give the same space between all the perforations on the paper in all the rows, the holes alternating in position in the different rows.

The punch 70 is set in the end of a vertical post, 7c, and works into the bed Z, (see Fig. 1,) and is operated by the punch-bar e and the lever-handle f, the bar having a slanting slot, m, at the end, in which pin a, attached to post 70, works, as in Fig. 1. Drawing the lever f toward the operator raises the punch, and at the same moment moves the carriage B one notch sidewise. Pushing the lever back forces the punch down, and at the same time drops the ratchet (2 into the next notch or tooth on rack c, and so on. To draw the ratchet-bar (I back to raise it out of the notch and to insure it dropping into the rack at the next movement just one tooth, I attach to the punch-bar c an arm, 1), which projects out at right angles a little way. On the under side of this is a hollow slide or guide, 0-, which works on a slanting piece, 8, pivoted to the top of the ratchet-bar d at a slant. Thus every time the punch-bar e is drawn back, the guide 1- draws forward the ratchet-bar d by the piece 8, (shown fully in Fig. 3,);and pushes the carriage B forward one notch. Vhen run clear through, the bar (I is raised by hand, at the same time pulling out a little way the wedges w 10. Then the carriage is pushed back for a new row of perforations to be made. This wedge w sets in the vertical pieces to which the links y y are attached, and which hold the ratchet d suspended. It regulates the distance that the ratchet shall fall. (See Fig. 1.)

The guide 1' may be set at a greater or less angle, to correspond to the distance required by the paper between the perforations, and the rack c and wheel r will all be changed to correspond. The angle 01' the guide 1' is changed by the pin u at the top. This is important, as it will cause the carriage I to go a little farther or not so far, as required by the size of the perforations to be made. The punch is of course raised before the carriage starts, otherwise it would tear the paper.

I am aware that there are many devices for punching and perforating paper for various purposes, but nothing like mine.

I clai1n-- 1. The combination, in one machine, of the punching devices 0 7r 7; m n. the carriage B,

having the rack c, the ratchet-bar (Z d, and the guide p 1' s u, all operated by the lever f, substantially as and for the purpose specified.

2. In combination with the punching devices f c 7r 7; and carriage B, the ratchet-Wheel 1 grooved wheel g, ratchet 'i lever j, and rope h I), for drawing said carriage forward, all arranged and operating substantially as and for the purpose specified.

In testimony whereof I alllx my signature, in presence of two witnesses, this 9th day of February, 1883.
